27059

27059 is a FS-200 series flow switch. It offers accurate flow detection, with 1% repeatability, over a broad range of flow settings and port sizes. Its durable construction delivers long-life reliability in either water or oil. Generous flow paths keep the pressure drop low. This switch is ideal for the detection of improper flow rates in high-volume lubrication, cooling or process systems. Applications include protecting bearings or gears (oil separators, fuel systems, pumps, compressors, presses), electronics or machinery (heat exchangers, semiconductor manufacturing equipment, induction furnaces, radio transmitters), process systems (water filtration and reverse osmosis, chlorinators, de-icers, sterilizers, evaporators).
